Description
II
Изобретение относитс к цветной мегаллургии , а именно к способам переработки шлаков, и может быть использовано щ)и обеднении медьсодержащих щлаков.The invention relates to colored megalurgy, namely to methods for the processing of slags, and can be used (n) and the depletion of copper-containing slag.
Наиболее близким по технической сущности и достигаемому результату вл етс способ,переработки медьсодержащих шлаков, вкпючЕающий плавку с добавкой кальцийсодержащего реагента и кокси- .The closest in technical essence and the achieved result is the method of processing copper-containing slags, which includes melting with the addition of calcium-containing reagent and coke-.
Недостатки известного способа состо т в продолжительности iqjouecca обеднени (2 ч) и в необходимости дл получени расплава, пригодного дл изготовлени строительных материалов, осуществл ть процесс переработки в две стадии, что требует дополнительных затрат электроэнергии и времени (врем второй стадии 2-3 ч).The disadvantages of this method are the duration of depletion iqjouecca (2 hours) and the need to obtain a melt suitable for the manufacture of building materials, to carry out the processing process in two stages, which requires additional power and time (the second stage is 2-3 hours) .
Целью изобретени вл етс интенсификаци щ)оцесса переработки шлаков и совмещение его с получением расплавов, 1ФИГОДНЫХ дл изготовлени строительных материалов.The aim of the invention is to intensify the process of slag processing and to combine it with the production of melts, 1F for the manufacture of building materials.
Поставленна цель достигаетс тем, что согласно способу переработки медьсодержащих шлаков, включающему плавку с добавкой кальцийсодержащего реагента и коксика, в качестве реагента используют 10-1ОО%,от веса шлака окисленную цинковую руду, содержащую, вес.%: Цинк.4-12The goal is achieved by the fact that according to the method of processing copper-containing slags, including smelting with the addition of calcium-containing reagent and coke, 10-1OO% are used as a reagent, based on the weight of the slag, oxidized zinc ore, containing, wt.%: Zinc.4-12

Сущность предложенного способа за15 ключаетс в следующем.The essence of the proposed method is as follows.
Процесс осуществл етс при 1200125О с . Наличие в руде окислов магни и окислов кальци , а также присутствие в восстановительной шихте кокснка, бла20 гопри тствует образованию карбидов магни и кальци , вл ющихс интенсивными восстановител ми. Взаимодействие непрерывно получаемых карбидов с комThe process is carried out at 1200125O. The presence of magnesium oxides and calcium oxides in the ore, as well as the presence of a coxnink in the reduction mixture, favors the formation of magnesium and calcium carbides, which are intensive reducing agents. The interaction of continuously produced carbides with com
